Farnum & Loftin: Distribution of P. curvatus and P. tricuspis in Arkansas 15 DISTRIBUTION OF PSEUDACTEON CURVATUS AND PSEUDACTEON TRICUSPIS (DIPTERA: PHORIDAE) IN ARKANSAS

چکیده
From 1995 to 2009, four Pseudacteon species were released in the U.S. with 3 species, P. curvatus , P. tricuspis , and P. obtusus released in Arkansas. To determine Pseudacteon establishment and expansion, sticky traps were used to monitor phorid fly species at and near 10 release sites, in counties bordering neighboring states, and along regional transects. Pseudacteon flies were captured in 16 Arkansas counties: Ashley, Chicot, Clark, Desha, Drew, Hempstead, Howard, Little River, Montgomery, Nevada, Perry, Phillips, Pike, Polk, Sevier, and Union. Pseudacteon curvatus was found in areas far from release sites, suggesting dispersal from neighboring states. The range of P. tricuspis evidently also expanded from its initial release sites in southern Arkansas.

Cytogenetic analysis of three species of Pseudacteon (Diptera, Phoridae) parasitoids of the fire ants using standard and molecular techniques
Pseudacteon flies, parasitoids of worker ants, are being intensively studied as potentially effective agents in the biological control of the invasive pest fire ant genus Solenopsis (Hymenoptera: Formicidae). This is the first attempt to describe the karyotype of P. curvatus Borgmeier, P. nocens Borgmeier and P. tricuspis Borgmeier. The three species possess 2n = 6; chromosomes I and II were me...

Natural enemies of the imported fire ants, Solenopsis invicta Buren S. richteri Forel (Hymenoptera: Formicidae), and their hybrid, include a suite of more than 20 fire ant decapitating phorid flies from South America in the genus Pseudacteon. Over the past 12 years, many researchers and associates have cooperated in introducing several species as classical or self-sustaining biological control ...

p 1 Host specificity of the decapitating fly Pseudacteon curvatus was studied to determine whether this species is suitable for release as a classical biocontrol agent of imported fire ants in the United States. A series of no-choice tests with 19 species of ants from 12 genera showed that P. curvatus will not develop in ants outside the genus Solenopsis. P. curvatus successfully parasitized th...

Lactic acid bacteria (LAB) have historically been used in food fermentations to preserve foods and are generally-recognized-as-safe (GRAS) by the FDA for use as food ingredients. In addition to lactic acid; some strains also produce bacteriocins that have been proposed for use as food preservatives. In this study we examined the inhibition of Listeria monocytogenes 39-2 by neutralized and non-n...
